- Scientists from the British Antarctic Survey are drilling ice cores in the Antarctic and analysing them to find out what the Earth's temperature and carbon dioxide levels were like in the past.
In this video, Ice Core Scientist Nerilie Abram reveals how we recover and study ice through the ages, and how this gives us an insight into how the Earth's climate is changing.
00:00 Intro
00:20 What is it like on an Antarctic Survey expedition?
00:52 How do you drill ice cores?
01:28 How is the climate changing in Antarctica?
01:43 What can we learn from ice cores?

Literally everyone here is for science/geography homework :p
yup.
Me too
Yes
yessir
same I have to do a worksheet that is based on this video 😅🙂
Who is forced here for homework? Like if you are here for home work too.
SAMMME
HAHHAHAHAHA now i can relate...
Me ahah
I'm here for a science
Here for a geography
i had to watch this for geography homework lol
same
@@tomhague1 depression strikes back with hw
JustShiver tell me about it
Same haha
Ikr
It's kinda funny to think that most of the views are just the students who came here for homework whilst the smaller percentage is the teachers who found this video
Not me... 😁Just a truth seeker.
I just typed in "Ice cores for Younger Dryas", didn't find what I was most interested in but....
67000 views, 67000 forced to watch this to answer questions about some cold poles
yep
Had to do this for homework (4/20/2020)
i had to watch this for my science homework lol
Have to do this for geography
I had to watch this for science homework
I love how the didn’t mention the actual data…. Wonder why that is… lmao.
Because the earth was warmer 20k years ago than it is now, and that would take away money from the entire bullshit climate change argument.
Would it be bad to put 20000 year old ice cubes in your drink
Prob bacteriums so yeah maybe most likely not
Yummy ancient world ending bacteria
1) drill is pulled up and down by 1.5 meters, repeatedly until the bottom of the ice sheet is reached.
thank youu
Really? That's what I heard too. Cheers!
Thanks mate
nice to see all my other homework brothers
Thank you as this is the true science of factual material that tells a story.
What do you think is factual material?
🧐... True science + factual material = why we need to eat insects, live in 15 minute smart cities, and use cricket
flour for our pancakes and eat bioengineered food analogs and understand Greta Thornburg very well.
Thank you. I receive this scientism
programming. Yes. Yes. Yes.
I’m the only person in the comments who randomly searched for this video
nope .. i'm curious ..
Bruh moment
I am watching this video as part of my Climate Change and Sustainability Course in college. Not looking for specific answers to a homework assignment as many students below are (good luck students!) I'm tasked with increasing my understanding of the causes of climate change. Was nice to see a physical ice bore sample with the visible air bubbles (after cutting a slice). Next, I'll look for a similar video of ocean sediment cores that look at carbonates from fossils of plankton.
Glad it's been useful! 🦖

10 years later. May I ask: What do they find out?
@@mathematiknet
You will find the answer in this youtube video of the actual scientists discussing their discoveries.

Natural History Museum: wow, so many views

: don't say wow to that, so many views equals so many people being forced to watch their video because of their homework
lol
this is my dream job!
Another one here for homework :). I love oceanography ;)
2:00 Cool pic
Who's here for quarantine work
help my wifi is slow and i have to watch this for my online homework dml
too much long words such as ice cores :( help plz

Time stamping for hw hahahah... kill me
I watched this for geography class!! 🤠 anyone else?!
me lol, I'm from Belgium
1875 was the coldest time in last 10,000 years..so of course the temerature is rising. Looking at ice core sample graphs you see the same pattern, up and down the ebb and flow of natural cyclic variation.
Except that natural cyclic variation takes millennia to happen, whereas the current climate change has happened in the course of about a century. Also, natural periods of global warming match increases of greenhouse gases in the atmosphere; the current man-made increase of greenhouse gases in the atmosphere is causing the same effect. Didn't you listen to what the researcher said? How is it that a bystander is certain he knows better than a scientist about her own field of study?
Claiming that the current man-made climate change, with all the catastrophic effects we are watching on a daily basis (and the mass extinctions that make no headlines) is of no importance, or cannot, or should not be mitigated because such events have happened before naturally, is like a man who, on the basis that wildfires happen naturally, sets fire to his own house, not having another place to go, and refuses to use the extinguisher he owns, or even the garden hose - and refuses to heed the firefighters.
Yes
uhh "yay" science make up from 18 days ago! That i'm doing mid Christmas break...
Visible light is electromagnetic, short wave photonic energy. When it strikes the surface of the Earth, that which is not reflected away into space is absorbed and converted into heat (infrared energy). This heat is conducted throughout the material that absorbed it. Any air that comes into direct contact with it absorbs some of it via conduction and is then convected away. The remainder of the heat from the material’s surface is emitted away as infrared long waved radiation which passes freely through the small moleculed atmospheric gases of nitrogen, oxygen and argon. However, the larger atmospheric molecules such as carbon dioxide, water vapor, methane, etcetera have a quantum mechanics based affinity for absorbing and re-emitting this infrared radiation - thus, slowing down its escape into space. It is this blanketing effect on infrared radiation that makes life on Earth possible - for without it there could be no liquid water on the planet.

Life as we know it and liquid water covering the surface but don't forget that the earth is hot deep inside. The planet is a ball of hot rock with a liquid magma core.
@@dickinstheblackcactu it is, but virtually all heating on the surface comes from the sun. That's why water from a fountain is cold, not hot.
Yo 9S where u at????
100k students forced to watch this, nice. (12/6/20)
ZuccTheFirst bruh
LOVELY JUBBLY🎉🎉
This video was in my ecology lecture haha
Tomorrow ( August 17th) I’m going to get a 100 on the TOEFL
I wanna take some of that ancient ice and make a snow cone
and what was the climate like that cause miles of ice to cover a continent ?
one day they gonna run out of ice
POV: ur here from mr henderson's lesson
shush
AAAAAAAAHHH!
Hello class
I’m here for school work 😢
me too
I have to watch this for environment homework
yoo what up ppl
fix your camera settings
@@pauciloquy yo leave me alone
MMS kids where you at??
AHHHHHH SCIENCE HW
We need to look back much much further to see what the effect is of human society on the earth’s continuously changing temp. Hundreds of thousands of years to really see where we stand instead
Further than what? How much impact do you think the few hundred thousand humanoids that roamed the Earth twenty thousand years ago had on its climate - and why?
Industrial Revolution, anyone?
here for homework ;-;
Who is here for geography homework 😂
hi guys, i-i t-think you a-are really k-kachaan
it’s now 2020 and i’m also here for homework lmao 😭
you look so familliar!!!!
The correct answer is "There is no spoon"
111,301 views just for hw / class work
There were no greenhouse gases 10.000 years ago!! Only the temperature of the ice is relevant and of course you dont say that 1875 was the coldest year in 10.000 years

geography homework amiright?
ok,, so what is this study saying, lets see a graph of weather change...
Great technical job but extremely poor science!
The null hypothesis that co2 controls climate is false and you will tell nothing about what future climate will be with co2 analysis.
The hypothesis that climate controls co2 production through photosynthesis is the correct hypothesis.
As temperature increases photosynthesis increases and animals flourish putting more co2 into the atmosphere.
As temperature declines plant production decreases and land available for plant production decreases thus Animal populations and co2 production decreases lessing co2 in the atmosphere!
Now measure in the total loss of tropical forest density and explain why CO2 levels have increased. I'm confused
@JohnEboyee Tropical forests emit oxygen and take in C02 and when removed are not there to prevent the sun from warming the earths surface. The only thing to measure is the contribution to warming caused by forest depletion.
@@wilsoniakennelgoldens2259 Let's take a plant and put it in a box. That plant utilizes available CO2 during the day for photosynthesis, then emits part of said CO2 at night called respiration. The total output of CO2 is less than what was taken in to grow now leading to less CO2 in the box.
Now let's take CO2 and put it in an empty box.
everyone forced for homework dislike this video
Nerd alert 🚨 not here for homework
Not much information in this Video. Sounds like propaganda.
So the earth heats up and cools down over time and has done forever... No more global warming nonsense
I had to watch this for science 🧪 ugh 🤦🏻♀️
so you tell us nothing!
A very superficial video
Just UNDERSTAND it is possibility NOT facts.
